The McGurk Effect
Here's another interesting audio illusion. Play the clip several times, alternating between looking at the talking head while listening, and listening with your eyes shut. Most adults (98%) think they are hearing "DA" - a so called "fused respons" - where the "D" is a result of an audio-visual illusion. In reality you are hearing the sound "BA", while you are looking at the lip movements "GA". It's called the McGurk effect.
